Luigi Client

This document outlines the features provided by the Luigi Client API. It covers these topics:

• Lifecycle - functions that define the lifecycle of different Luigi elements
• Callbacks - callback functions for initListener and customMessageListener
• Link manager - you can use the linkManager instead of an internal router
• Split view - allows you to open a micro frontend in the lower part of the content area in a "split screen" view
• uxManager - functions related to user interface
• storageManager - Storage Manager API to store/retrieve objects from Luigi Core local storage

API Reference

Lifecycle

Use the functions and parameters to define the Lifecycle of listeners, navigation nodes, and Event data.

isLuigiClientInitialized

Check if LuigiClient is initialized

Examples

const init = LuigiClient.isLuigiClientInitialized()

Returns boolean client initialized state

Meta

• since: 1.12.0

luigiClientInit

Starts the handshake with Luigi Core and thereafter resulting in initialization of Luigi Client. It is always ran by default when importing luigi-client package in your micro frontend. Note that when using 'defer-luigi-init' to defer default initialization you will need to initialize the handshake using this function manually wherever needed.

Examples

LuigiClient.luigiClientInit()

Meta

• since: 1.12.0

addInitListener

Registers a listener called with the context object and the Luigi Core domain as soon as Luigi is instantiated. Defer your application bootstrap if you depend on authentication data coming from Luigi.

Parameters

• initFn Lifecycle~initListenerCallback the function that is called once Luigi is initialized, receives current context and origin as parameters

Examples

const initListenerId = LuigiClient.addInitListener((context) => storeContextToMF(context))

removeInitListener

Removes an init listener.

Parameters

• id string the id that was returned by the addInitListener function.

Examples

LuigiClient.removeInitListener(initListenerId)

addContextUpdateListener

Registers a listener called with the context object when the URL is changed. For example, you can use this when changing environments in a context switcher in order for the micro frontend to do an API call to the environment picked.

Parameters

• contextUpdatedFn function the listener function called each time Luigi context changes

Examples

const updateListenerId = LuigiClient.addContextUpdateListener((context) => storeContextToMF(context))

removeContextUpdateListener

Removes a context update listener.

Parameters

• id string the id that was returned by the addContextUpdateListener function

Examples

LuigiClient.removeContextUpdateListener(updateListenerId)

addInactiveListener

Registers a listener called upon micro frontend inactivity. This happens when a new micro frontend gets shown while keeping the old one cached. Gets called when:

• navigating with preserveView
• navigating from or to a viewGroup

Does not get called when navigating normally, or when openAsModal or openAsSplitView are used. Once the micro frontend turns back into active state, the addContextUpdateListener receives an updated context.

Parameters

• inactiveFn function the listener function called each time a micro frontend turns into an inactive state

Examples

LuigiClient.addInactiveListener(() => mfIsInactive = true)
const inactiveListenerId = LuigiClient.addInactiveListener(() => mfIsInactive = true)

removeInactiveListener

Removes a listener for inactive micro frontends.

Parameters

• id string the id that was returned by the addInactiveListener function

Examples

LuigiClient.removeInactiveListener(inactiveListenerId)

addCustomMessageListener

Registers a listener called when the micro frontend receives a custom message.

Parameters

• customMessageId string the custom message id
• customMessageListener Lifecycle~customMessageListenerCallback the function that is called when the micro frontend receives the corresponding event

Examples

const customMsgId = LuigiClient.addCustomMessageListener('myapp.project-updated', (data) => doSomething(data))

Meta

• since: 0.6.2

removeCustomMessageListener

Removes a custom message listener.

Parameters

• id string the id that was returned by the addInitListener function

Meta

• since: 0.6.2 LuigiClient.removeCustomMessageListener(customMsgId)

getToken

Returns the currently valid access token.

Examples

const accessToken = LuigiClient.getToken()

Returns string current access token

getContext

Returns the context object. Typically it is not required as the addContextUpdateListener() receives the same values.

Examples

const context = LuigiClient.getContext()

Returns Object current context data

getEventData

Returns the context object. It is an alias function for getContext().

Returns Object current context data

Meta

• deprecated: This is deprecated.

getActiveFeatureToggles

Returns a list of active feature toggles

Examples

const activeFeatureToggleList = LuigiClient.getActiveFeatureToggles()

Returns Array a list of feature toggle names

Meta

• since: 1.4.0

getNodeParams

Returns the node parameters of the active URL. Node parameters are defined like URL query parameters but with a specific prefix allowing Luigi to pass them to the micro frontend view. The default prefix is ~ and you can use it in the following way: https://my.luigi.app/home/products?~sort=asc~page=3.

NOTE: some special characters (<, >, ", ', /) in node parameters are HTML-encoded.

Examples

const nodeParams = LuigiClient.getNodeParams()

Returns Object node parameters, where the object property name is the node parameter name without the prefix, and its value is the value of the node parameter. For example {sort: 'asc', page: 3}

getPathParams

Returns the dynamic path parameters of the active URL. Path parameters are defined by navigation nodes with a dynamic pathSegment value starting with :, such as productId. All path parameters in the current navigation path (as defined by the active URL) are returned.

NOTE: some special characters (<, >, ", ', /) in path parameters are HTML-encoded.

Examples

const pathParams = LuigiClient.getPathParams()

Returns Object path parameters, where the object property name is the path parameter name without the prefix, and its value is the actual value of the path parameter. For example {productId: 1234, ...}

getCoreSearchParams

Read search query parameters which are sent from Luigi Core

Examples

LuigiClient.getCoreSearchParams();

Returns any Core search query parameters

addCoreSearchParams

Sends search query parameters to Luigi Core. If they are allowed on node level, the search parameters will be added to the URL.

Parameters

• searchParams Object

Examples

LuigiClient.addCoreSearchParams({luigi:'rocks'});

getClientPermissions

Returns the current client permissions as specified in the navigation node or an empty object. For details, see Node parameters.

Examples

const permissions = LuigiClient.getClientPermissions()

Returns Object client permissions as specified in the navigation node

setTargetOrigin

When the micro frontend is not embedded in the Luigi Core application and there is no init handshake you can set the target origin that is used in postMessage function calls by Luigi Client. Typically used only in custom micro-frontend frameworks that are compatible with LuigiClient API.

Parameters

• origin string target origin

Examples

LuigiClient.setTargetOrigin(window.location.origin)

Meta

• since: 0.7.3

sendCustomMessage

Sends a custom message to the Luigi Core application.

Parameters

• message Object an object containing data to be sent to the Luigi Core to process it further. This object is set as an input parameter of the custom message listener on the Luigi Core side

  • customMessage.id string message id
  • customMessage.MY_DATA_FIELD any any other message data field
• listenerId string custom message listener id to be used for unsubscription

linkManager

The Link Manager allows you to navigate to another route. Use it instead of an internal router to:

• Provide routing inside micro frontends.
• Reflect the route.
• Keep the navigation state in Luigi.

navigateToIntent

Offers an alternative way of navigating with intents. This involves specifying a semanticSlug and an object containing parameters. This method internally generates a URL of the form #?intent=<semantic object>-<action>?<param_name>=<param_value> through the given input arguments. This then follows a call to the original linkManager.navigate(...) function. Consequently, the following calls shall have the exact same effect:

• linkManager().navigateToIntent('Sales-settings', {project: 'pr2', user: 'john'})
• linkManager().navigate('/#?intent=Sales-settings?project=pr2&user=john')

Parameters

• semanticSlug string concatenation of semantic object and action connected with a dash (-), i.e.: <semanticObject>-<action>
• params Object an object representing all the parameters passed, i.e.: {param1: '1', param2: 2, param3: 'value3'}. (optional, default {})

Examples

LuigiClient.linkManager().navigateToIntent('Sales-settings', {project: 'pr2', user: 'john'})
LuigiClient.linkManager().navigateToIntent('Sales-settings')

withoutSync

Disables the navigation handling for a single navigation request It prevents Luigi Core from handling url change after navigate(). Used for auto-navigation

Examples

LuigiClient.linkManager().withoutSync().navigate('/projects/xy/foobar');
LuigiClient.linkManager().withoutSync().fromClosestContext().navigate('settings');

Meta

• since: 0.7.7

newTab

Enables navigating to a new tab.

Examples

LuigiClient.linkManager().newTab().navigate('/projects/xy/foobar');

Meta

• since: NEXT_RELEASE

preserveQueryParams

Keeps the URL's query parameters for a navigation request.

Parameters

• preserve boolean By default, it is set to false. If it is set to true, the URL's query parameters will be kept after navigation. (optional, default false)

Examples

LuigiClient.linkManager().preserveQueryParams(true).navigate('/projects/xy/foobar');
LuigiClient.linkManager().preserveQueryParams(false).navigate('/projects/xy/foobar');

Meta

• since: NEXT_RELEASE

navigate

Navigates to the given path in the application hosted by Luigi. It contains either a full absolute path or a relative path without a leading slash that uses the active route as a base. This is the standard navigation.

Parameters

• path string path to be navigated to
• sessionId string current Luigi sessionId
• preserveView boolean preserve a view by setting it to true. It keeps the current view opened in the background and opens the new route in a new frame. Use the goBack() function to navigate back. You can use this feature across different levels. Preserved views are discarded as soon as you use the standard navigate() function instead of goBack()

storageManager

StorageManager allows you to use browser local storage of key/values. Every storage operation is sent to be managed by Luigi Core. The idea is that different micro frontends can share or persist items using local storage. Since all storage operations are asynchronous (sending an event to Luigi Core that will reply once operation is finished), all the methods return Promises.

Examples

LuigiClient.storageManager().setItem('keyExample','valueExample').then(() => console.log('Value stored'))

Returns Promise<void> resolves an empty value when the storage operation is over. It will launch an error if storage is not supported, the value cannot be stringified, or if you are using a Luigi reserved key.

Meta

• since: 1.6.0

getItem

Retrieves an item for a specific key.

Parameters

• key string used to identify the value

Examples

LuigiClient.storageManager().getItem('keyExample').then((value) => console.log);

Returns Promise<Object> resolves an item retrieved from storage. It will launch an error if storage is not supported.

Meta

• since: 1.6.0

removeItem

Removes an item for a specific key.

Parameters

• key string used to identify the value

Examples

LuigiClient.storageManager().removeItem('keyExample').then((value) => console.log(value + ' just removed')

Returns Promise<Object> resolves an item just removed from storage. It will launch an error if storage is not supported or if you are using a Luigi reserved key.
